More information has been released from Microsoft about the various editions of Windows 10 that will be shipped. In all, there will be 7 primary versions of Windows 10.
The first two are probably the most expected: Home and Pro. Home features all of the main highlights of Windows 10: Cortana, the Microsoft Edge web browser, greater Xbox integration, and Windows Continuum for touch-enabled devices.
To those features, Pro adds tools for using and managing Windows 10 in a small business setting. It includes Windows Update for Business, and the ability to join Active Directory domains.
